Frequency Setting By Analog Input (Terminal 1, 2, 4); Analog Input Selection (Pr.73, Pr.267) - Mitsubishi Electric F700 Instruction Manual

3.15 Frequency setting by analog input (terminal 1, 2, 4)

Purpose
Selection of voltage/current input
(terminal 1, 2, 4) Perform forward/
reverse rotation by analog input.
Adjust the main speed by analog
auxiliary input.
Noise elimination at the analog input Input filter
Adjustment (calibration) of analog
input frequency and voltage
(current)

3.15.1 Analog input selection (Pr.73, Pr.267)

You can select the function that switches between forward rotation and reverse rotation according to the
analog input selection specifications, the override function and the input signal polarity.

The above parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 140)
(1) Selection of analog input selection
⋅ For the terminals 1, 2, 4 used for analog input, voltage input (0 to 5V, 0 to 10V) or current input (4 to 20mA) can
be selected.
